CENTRIFUGAL DRIER.

SPEGIFCATION forming part of Letters Patent No. "(45,223, dated. November24, 1903.

Application filed March I4, 1903. Serial No. 147.714. (No model.)

To a/ZZ whom t may concern:

Be it known that I, HENRY MQNK, of Cambridge, county of Essex, State of Massachusetts, have invented an Improvement in Oentrifugal Extractors, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

'This invention relates to certain improvements in that class Vof centrifugal extractors which are employed in laundries to extract water from clothes.

So far as I am aware, in operating the centrifugal extractors now in general use in laundries it is necessary to `throw the clothes to be dried intoa machine a few pieces at a time and then arrange them as evenly as possible before starting it again and to remove them in like manner. In this way considerable time is consumed, during which the machine must be idle.

The object of my invention isto facilitate the loading and unloading of such extractors, so that more clothes may be dried with a single machine in a given time than With the class of machines above referred to.

A further object of my invention is to provide improved vmeans for transmitting the power from the overhead counter-shaft to an extractor of the character above referred to, as hereinafter explained.

In the drawings, Figurel is a side elevation of a centrifugal extractor provided with my improvements. Fig.f2 is a vertical central section thereof. Figs. 3 and 4 are plan views of the holder and basket, respectively.

The centrifugal extractor is provided with the usual circular outer casing et', which is rigidly supported by legs b, said casing having its bottom dished and provided with a central circular opening a. A dischargepipe a2 leads from the lowest point in the bottom. A hollow frusto-conical-shaped standard c, having a bearing d secured in its upper end, is arranged concentric with said casing, and a vertical shaft e is journaled in said bearing, its lower end being stepped in a bearing e. A circular carrier f is centrally secured to the upper end of the shaft e). Said carrier has a solid conical-shaped bottom, and a series of vertical arms j extend upward from the edge thereof.

Vket is placed in the carrier it will be perfectly centered. The basket is provided with a series of circumferential strengthening-hoops g3 and longitudinal ribs g4, andthe upper end of its sides are bentinwardly. Two baskets are provided for each machine.

The means which I employ for rotating shaft e of the carrier comprises a vertical shaft h, which is stepped and journaled in the bearing t' and journaled in a bearing j, secured to the casing @,and a bearing it, secured to the ceiling. A loose pulley mis arranged on the upper eud'of shaft h, said pulley being driven by any suitable arrangement of belting from the counter-shaft. Said pulley The comprises one member of a clutch, the other member n being` splined on the shaft h. A lever o may beexnployed to force the clutch members together. A pulley 1o is secured to the lower end of .shaft h, and a belt q passes about the sameand a pulleyr on shaft e. The standards is provided with an opening to permit the passage ofthe belt', and the belt and pulley p are inclosed bya suitable housing s. The bearing j is provided with upper and lower extensions] jg, and tubular housings t t are respectively secured to said extensions and completely inclose shaftfh both above and below the bearing j. The driving means for the extractor is thus completely inclosed, so that it is impossible for the operator to become injured thereby or entangled therein. This driving means also occupies a minimum amount of space.

In operating the machine the basket,which has been previously removed, is filled with wet clothes, and then it is lifted by a conveniently arranged derrick or other suitable means and lowered into the carrier. Suitable attaching means, which may be readily detached, as hooks, (see dotted lines, Fig. 2,)

may be employed. The carrier is then rotated, carrying the basket with it, and the waier is extracted from the clothes by centrifugal force in the usual manner. When the water has been extracted, the basket is lifted from the carrier, and another basket, which has been in the meantime filled with wet clothes, is placed therein. In this way but little time is lost in transferring the clothes, with the result that a less number of machines are required to do the same work than if the basket could not be removed.

By providing the centering-head on the carriershaft e, which enters the centeringrecess of the basket, the latter will be held in a perfectly central position While it is being rotated, so that there will be as little vibration as possible.

By providing the frustum-shaped standard e with the bearing in its upper end closely adjacent the bottom of the carrier the carrier-shaft will be held as rigidly as possible from vibration when it is rotated.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

l. A centrifugal extractor comprising the stationary outer casing, a circular carrier open at its upper end, a vertical rotatable shaft on which said carrier is centrally mounted, and a circular perforated basket arranged within said carrier and removable therefrom in a vertical direction, substantially as described.

2. A centrifugal extractor comprising the stationary outer casing, a circular carrier open at its upper end, a vertical rotatable shaft on which said carrier is centrally mounted, said shaft extending through and above the bottom of the carrier, and a circular perforated basketinsertible at the upper end of the carrier, said basket having a centering-recess in the middle of its bottom in which the upper end of said shaft is litted and located, substantially as described.

3. In a centrifugal extractor, the fixed outer casing having the circular basket, a vertical shaft on which said basket is mounted, a hollow frusto-conical-shaped standard surrounding said shaft having a bearing in its upper end adjacent the bottom of the basket, a bearing for the lower end of said shaft and means for rotating said shaft, substantially as described.

4.' In combination with a centrifugal extractor, having a vertical shaft bearing a basket at its upper end, a rigid stationary casing surrounding said basket, a vertical drivingshaft arranged adjacent said casing, a vertically-arranged bearing secured to one side of said casing in which said driving-shaft is journaled, a bearing for the lower ends of both of said shafts, and a driving-gear between the lower end portions of said shafts, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HENRY MONK.
